That looks like regular SQL (DDL to create tables), not PL/SQL (which is used for stored procedures.)

In any case, what error are you getting?

The SQL in the first post and the most recent are not the same.  Try running the statements one at a time to troubleshoot. Does this work? (Make sure to include the semi-colon).

CREATE TABLE EMPLOYEES ( EMPLOYEE_ID VARCHAR2(20), FIRST_NAME VARCHAR2(50), LAST_NAME VARCHAR2(50), STREET_ADDRESS VARCHAR2(50), CITY VARCHAR2(50), POST_CODE VARCHAR2(50), PHONE_NUMBER VARCHAR2(50), WORK_NUMBER VARCHAR2(50), NI_NUMBER VARCHAR2(50), EMAIL VARCHAR2(50), CONSTRAINT EMPLOYEES_PRIMARY_KEY PRIMARY KEY (EMPLOYEE_ID))) ;

If that gives the same error, try these simpler ones (remember to run DROP TABLE EMPLOYEES in between)

CREATE TABLE EMPLOYEES ( EMPLOYEE_ID VARCHAR2(20), FIRST_NAME VARCHAR2(50), LAST_NAME VARCHAR2(50), STREET_ADDRESS VARCHAR2(50), CITY VARCHAR2(50), POST_CODE VARCHAR2(50), PHONE_NUMBER VARCHAR2(50), WORK_NUMBER VARCHAR2(50), NI_NUMBER VARCHAR2(50), EMAIL VARCHAR2(50)) ;

CREATE TABLE EMPLOYEES ( EMPLOYEE_ID VARCHAR2(20)) ;

Knowing which of these work and which don't will narrow down the problem nicely. (My guess is they will all work and you were just missing the semi-colon)

Your brackets don't seem to match.
At least for the Employee and Supplier ones.

After that, you seem to be attempting to create the Department table before the Supplier table, which it references, which is not allowed.

That's as far as I got.

So, check your brackets, and ensure you are creating your tables in the right order.
